Storm Impacting the Northwest U.S.; Fire Weather Conditions in Southern California; Severe Weather in the South

A Pacific storm is bringing areas of low elevation rain, moderate to heavy mountain snow, and high winds to the Northwest. Strong Santa Ana winds and very dry conditions are producing elevated to critical fire weather conditions in southern California. Isolated strong to severe thunderstorms are possible through early Wednesday morning across parts of northeast Texas into western Tennessee. Read More >

An area of low pressure moved across southern Canada to northern Lake Superior during the day and night of the 20th. As the low progressed east, it dragged a warm front across the Upper Midwest. Light snow developed well east of the warm front during the early morning hours of the 20th and continued through sunrise. Accumulations from this first round of snow ranged from a trace up to 3 inches. As the warm front passed through the region, an upper level disturbance moved across the Upper Midwest. The combination of these two features caused a narrow but intense band of snow to develop during the late morning hours. This band of snow continued through the afternoon into the evening and dropped up to 8 to 9 inches of snow across parts of central Wisconsin.

Around the local area, the band of the heaviest snow extended from eastern Mower county in Minnesota, through the La Crosse area into northern Adams and Juneau counties of central Wisconsin. The highest snowfall totals reported were 9 inches at Lake Camelot, Wisconsin and 8 inches at Arkdale, Wisconsin.


Snow totals for December 20.
